metamorphic rocks are a bit harder to identify because they can share traits with the other rock types. again, thinking about the formation process can help. metamorphic rocks have been heated and squashed. this can lead the minerals in them to line up, creating ribbon - like layers called bands. these rocks are called foliated metamorphic rocks. you can see these bands in gneiss. if a metamorphic rock has fossils, you know it was formed from a sedimentary rock. because of the heat and pressure, the fossil will be hard to recognize and out of shape. which of the following best describes foliated metamorphic rocks? choose one option a there are easily recognizable fossils. b the rock has ribbon - like layers of bands. c they have crystals like igneous rocks. d different sized sediments can be seen.

Answer

Brief Explanations:

The text states that "Metamorphic rocks have been heated and squashed. This can lead the minerals in them to line up, creating ribbon - like layers called bands. These rocks are called foliated metamorphic rocks." So, we need to check which option matches this description.

  • Option A: The text says "If a metamorphic rock has fossils...the fossil will be hard to recognize", so A is incorrect.
  • Option B: The text mentions "creating ribbon - like layers called bands" for foliated metamorphic rocks, which matches this option.
  • Option C: There is no mention of crystals like igneous rocks in the description of foliated metamorphic rocks.
  • Option D: Different - sized sediments are not described as a feature of foliated metamorphic rocks.

Answer:

B. The rock has ribbon - like layers of bands.
